> Looking at the source code, with my untrained python eyes, I think if the intention is to include the message id and the publish time in the attributes attribute of the PubSubMessage type, then the protobuf mapping is missing something:-
> @staticmethod
> def _from_proto_str(proto_msg):
> """Construct from serialized form of ``PubsubMessage``.
> Args:
> proto_msg: String containing a serialized protobuf of type
> https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.PubsubMessage
> Returns:
> A new PubsubMessage object.
> """
> msg = pubsub.types.pubsub_pb2.PubsubMessage()
> msg.ParseFromString(proto_msg)
> # Convert ScalarMapContainer to dict.
> attributes = dict((key, msg.attributes[key]) for key in msg.attributes)
> return PubsubMessage(msg.data, attributes)
> The protobuf definition is here:-
> https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.PubsubMessage
> and so it looks as if the message_id and publish_time are not being parsed as they are seperate from the attributes. Perhaps the PubsubMessage class needs expanding to include these as attributes, or they would need adding to the dictionary for attributes. This would only need doing for the _from_proto_str as obviously they would not need to be populated when transmitting a message to PubSub.
> My python is not great, I'm assuming the latter option would need to look something like this?
> attributes = dict((key, msg.attributes[key]) for key in msg.attributes)
> attributes.update({'message_id': msg.message_id, 'publish_time': msg.publish_time})
> return PubsubMessage(msg.data, attributes)
> """
